Split type high-strength receiver

Abstract

The invention provides a split type high-strength receiver. The split type high-strength receiver comprises a receiver upper part and a receiver lower part, wherein the receiver upper part comprises an upper casing, a vibrating diaphragm, a voice coil, and a torsion cover; the receiver lower part comprises a lower casing and a magnet; the receiver upper part and the receiver lower part are fastened through threads, and are sealed through butting grooves and butting blocks; the vibrating diaphragm and a notched terrace are clamped through a connecting sleeve for fixation, and are bonded for reinforcement; and the vibrating diaphragm comprises a fixed part and a middle part, connecting areas with connecting bulges are arranged on the fixed part, a strengthening groove and strengthening bumpsare arranged in the middle part, and connecting grooves are formed between the fixed part and the middle part. The split type high-strength receiver provided by the invention has the advantages thatthe receiver is divided into the upper part and the lower part for separation production, so that the mounting is convenient, and the fault tolerance rate is increased; through the strengthening groove and the strengthening bumps, the rigidity of the vibrating diaphragm can be improved, so that the vibrating diaphragm is unlikely to be damaged; through the connecting bulges, a fixed area of the vibrating diaphragm can be effectively enlarged, so that the connecting strength is improved, and low falling possibility is achieved; and the lower end surfaces of the connecting grooves are flat, so that quality inspection is facilitated after connection of the voice coil.

Description

technical field [0001] The invention relates to the field of receiver production, in particular to a split-type high-intensity receiver. Background technique [0002] The mobile phone receiver is an electro-acoustic device that converts electrical energy into sound energy. Simply put, it is a generator. At present, most of the receivers used in mobile phones are dynamic receivers, which use the mutual driving force between the magnetic field and the current-carrying conductor to drive the air around it. The vibration of the receiver generates sound waves, and the current-carrying conductor is the vibrating part of the receiver, and the vibrating part is composed of a diaphragm and a voice coil. [0003] Most of the receivers currently used are produced in a single-flow process, that is, on the basis of a single shell, they are installed sequentially from the inside to the outside. Due to the production requirements of the assembly line, in the production process, the really ...

Problems solved by technology

[0003] Most of the receivers currently used are produced in a single-flow process, that is, on the basis of a single shell, they are installed sequentially from the inside to the outside. Due to the production requirements of the assembly line, in the production process, the really necessary quality inspection can only be done in large Quality inspection is carried out after some parts are completed. During the reproduction process, if a certain process goes wrong, it will easily lead to batch scrapping, and the fault tolerance rate is low. At the same time, the traditional diaphragm generally has the problem of insufficient rigidity. However, in the production process, it is not uncommon for the position of the dome to shift. At the same time, with the use of the receiver, the dome will also fall off, which seriously affects the quality and service life of the receiver. At the same time, after the traditional diaphragm and voice coil are connected , the position of the voice coil is mostly manual quality inspection. During the quality inspection, unless the position deviates greatly, it is difficult to detect, and there is difficulty in quality inspection.
